CUSHN-TIRE.

Application filed January 13, 1921. Serial No.

To all r11/10m t may concern:

Be it lrnown Ithat I, BnNJAirrN C. SWINE- HART, a citizen of the United States, residing at Akron, in the county ot' Summit and State of Ohio, have invented new and useful improvements in Cushion-Tires, ci which the 'following is a specification.

This invention relates to a new and improved cushion tire which may be used on wheels generally. but which is particularly adapted to be employed to advantage on the wheels of selffpropelled vehicles.

Objects of the invention are to provide a tire of simple, economical construction which in use will be extremely eihcient in progress of a vehicle over a rough uneven surface..

A further object is to provide an annular elastic tire body provided with a circumferentially extending series of passages which are arranged therein so as to render the body more readily compressihle when subjected to a radially directed force.

An additional object is to provide a tire having a. plurality oi' passages or bores extending therethrough from its lateral sides to the peripheral face there-oic so as to permit a free circulation ot air through said passages and to thereby provide a tire which will not become ovcrheated even though subjected to continuous usage and driven at high Speed.

A further object is to provide a tire body having bores arranged therein as above set forth so that dirt. stones, snow, ice or other substance will be automatically expelled therefrom and to further provide a tire havingr a tread portieri which will be extremely c'ilicient in preventingslipping and skidding, even when used sufiiciently to wear away a considerable port-ion thereof.

The above objects are accomplished and additional ends are attained by the novel construction herein described and illustrated in the accompanying drawing` in which I have shown a preferred einbod1- ment of the invention, it being understood that various changes may he made in applying the principle herein disclosed and that changes and modifications may be made in the structure shown and described which come within the scope of the claims hereunto appended.'

In the drawing, l have t shown a single ligure which illustrates, in

portion of an elastic vehicle tire constructed in accordance with this invention and l have employed similar numerals of referlike or similar parts or things as the same appear therein.

ln the drawings, the numeral l has been employed to denote an annular elastic body preferably composed of rubber, rubber composition or the like. The numeral 2 is' used to indicate a rim which in the particular em bodiment of the invention shown constitutes a base ring to which the tire body is secured by vulcanization7 there being an intervening layer 8 of vulcanitc therebetween. r'he lateral sides el and 5 ol" the tire body converge from the base ring 3 to a relatively narrow peripheral face 6, rlhe tire body is provided on each lateral side with a circumferentially extending series of regularly recurring passages. Each passage projectings through the body oi the tire fom the lateral side to the peripheral or tread face thereof. The numeral 7-is used to denote the separate passages or bores in. the series or' passages extending; through the tire body from the lateral face 5 to the tread -lace 6 thcreoi2 and the numeral 8 is likewise employed to designate similar bores in the series oi passages which extend through the tire body Il `from the lateral 'lace i to the peripheral face 6 thereof. The passages 7 and 8, as shown in the drawing. are in the form of cylindrical bores which project into the tirs body in spaced relation to each other at points in spaced relation te the rim 2 and each bore extends upwardly from its respeeiie side oi the tire at an angle to the axis of the tire so as to form an elongated opening in the peripheral face o at a point in close spaced relation ro the opposite side oi the tire. The hores 7 and 8 are disposed in the tire so as to alternate with each 'other and with the axis of the bores 7 inclinedat an angle to the axis oi the bores 8.

While l have shown and described the passages 7 and 8 of cylindrical form, the passages may be of any desired cross sectional contour and while I have shown a tire body having sloping side walls, it is to be understood that the invention is not thus limited, nor limited to the particular form of rim shown nor to any particular method oi fas lening the tire body thereto.

It will thus be seen that lhave provided 'a strong, durable tire of simple, economical construction which in use will constitute en used on the wheels of vehicles without danger of slipping or-skidding.

Having thusdescribed my invention, l claim as new and desire to secure by Letters- Patent l. A cushion tire comprising an annular elastic body provided with holes extending therethrough from its lateral sides to the peripheral face thereof.

.2. Atire of the class described, comprisling an annular elastic body provided on each lateral side withv a circumferentiully extending series of regularly recurring holes which project therethrough to the peripheral face thereof.

3.- A tire of the class described comprising an annular elastic body provided on each lateral side with e circumferentinlly extending series of regularly recurring holes which project therethrough and terminate in the peripheral ,face thereof at points adjacent the opposite side of the tire body.

41. A tire of the class described comprising an annular elastic body having a Widebase, inclined lateral sides and a relatively narrow peripheral face and provided on each lateral side with a circumferentially extending series of regularly recurring,r holes projecting therethrough to the, peripheral face thereof.

5. A cushion tirs provided with a plurality of holes, eacheictending therethrough y from its tread face to a lateral side thereof, the holes in the tread face alternately disposed adjacent opposite edges thereof and alternately' directed to opposite sides of the tire.

ln testimony whereof I have hereunto set my hand.
